Avermectin and its analogues, produced by Streptomyces avermitilis, are major commercial antiparasitic agents in the field of animal health, agriculture, and human infections. They are 16-membered pentacyclic lactone compounds derived from polyketide and linked to a disaccharide of the methylated deoxysugar l-oleandrose. Labeling studies, analyses of the(More)
Twinning in cattle is a complex trait that is associated with economic loss and health issues such as abortion, dystocia, and reduced calf survival. Twinning-rate QTL have been detected previously on BTA5 in the North American Holstein and Norwegian dairy cattle populations and in a USDA herd selected for high twinning rate. In previous work with the North(More)
Linkage disequilibrium was estimated using 7119 single nucleotide polymorphism markers across the genome and 200 animals from the North American Holstein cattle population. The analysis of maternally inherited haplotypes revealed strong linkage disequilibrium (r(2) > 0.8) in genomic regions of approximately 50 kb or less. While linkage disequilibrium decays(More)
Twinning is a complex trait with negative impacts on health and reproduction, which cause economic loss in dairy production. Several twinning rate quantitative trait loci (QTL) have been detected in previous studies, but confidence intervals for QTL location are broad and many QTL are unreplicated. To identify genomic regions or genes associated with(More)
A previous genome-wide search with a moderate-density 10,000-SNP set identified many marker associations with twinning rate on BTA14 through either single-marker analysis or combined linkage-linkage disequilibrium (LLD; haplotype) analysis. The objective of the current study was to fine-map putative QTL using a more densely populated marker map and both a(More)
Two commercial, pure broiler lines with different susceptibility to coccidiosis were used to fine-map QTL associated with the previously identified marker LEI0101, located at 259 cM on chromosome 1 and shown to be significantly associated with disease resistance. Eight additional microsatellite markers linked to LEI0101 were used for genotyping of F(1)(More)
Our previous genetic studies demonstrated that resistance to avian coccidiosis is linked with microsatellite markers LEI0071 and LEI0101 on chromosome 1. In this study, the associations between parameters of resistance to coccidiosis and single nucleotide polymorphisms (SNP) in 3 candidate genes located between LEI0071 and LEI0101 [zyxin, CD4, and tumor(More)
Goats and sheep are versatile domesticates that have been integrated into diverse environments and production systems. Natural and artificial selection have shaped the variation in the two species, but natural selection has played the major role among indigenous flocks. To investigate signals of natural selection, we analyzed genotype data generated using(More)
A new object tracking mask-based novel-look-up-table (OTM-NLUT) method is proposed and implemented on graphics-processing-units (GPUs) for real-time generation of holographic videos of three-dimensional (3-D) scenes. Since the proposed method is designed to be matched with software and memory structures of the GPU, the number of(More)
Associations between the parameters of resistance to coccidiosis and SNP in 3 candidate genes located on chromosome 1 [T cell receptor-beta (TCR-beta), myeloid leukemia factor 2 (MLF2), and lymphotactin] were determined. Single nucleotide polymorphisms were genotyped in 24 F1 generation and 290 F2 generation birds. Four SNP were identified in the(More)
